FOAN Access Network Subsystems

In this chapter, we describe the state-of-the-art electro-optic active and passive components and devices predominately used in the design, testing, and deployment of FOANFuture Optical Access Network (FOAN), such as converged network adapters (CNAConverged Network Adapters (CNA)), all-optic devices based on low-loss materials such as planar waveguides, including couplers, circulators, multiplexers, filters, optical amplifiers, transmitters, detectors, wavelength converters, optical add-drop multiplexers (OADMOptical add-drop multiplexers (OADM)), optical cross-connectors (OXCOptical Cross-Connectors (OXC)), and wavelength converters. FOANFuture Optical Access Network (FOAN) will serve as the foundation for a unified and converged OANOptical Access Network (OAN). Multiple vendors’ data and services will be integrated, transported, and delivered via a common network infrastructure. Selection and integration strategies for CAN will be critical for protocol-independent and seamless application and service integration.
